I am a graduate student in computer science at the University of Illinois at Urbana-Champaign. I started in Fall 2007 and I am studying logic, automated deduction and program verification with Madhusudan Parthasarathy.

Before starting my studies at the University of Illinois I completed my Master studies at Nanjing University, China in the group of Xuandong Li.

Projects

Strand: A logic combining heap structures and data

Strand ("STRucture ANd Data") is a logic that allows reasoning with heap-manipulating programs using deductive verification and SMT solvers. More details can be found here).

Dryad: Recursive proofs for inductive tree data-structures

Dryad is a quantifier-free first-order logic over heaps augmented with recursive definitions of various types (e.g., an integer, a set/multiset of integers, etc.) defined for locations that have a tree under them. More details can be found here).
